Sumario:BACKGROUND: A duplicated middle cerebral artery (DMCA) is a rare vessel anomaly. Aneurysms at the origin of DMCA have been reported. CASE DESCRIPTION: We report 2 cases of aneurysms at the origin of DMCA accompanied by aneurysms at different sites. Each case of ruptured and unruptured aneurysm at the DMCA origin was associated with an unruptured aneurysm at the ipsilateral internal carotid artery and a ruptured one at the ipsilateral MCA, respectively. The aneurysms were clipped successfully in both patients. CONCLUSION: In cases of DMCA aneurysm associated with an aneurysm at another site, either aneurysm has a high risk of rupture. In such a case, radical treatment is necessary.
